Uyet Inc. runs three concurrent VTuber-facing programs: a survey of streamer health, a recurring free voice training webinar, and offline volunteer events through the Machi Supacha Project. The most recent story is the September 28 survey results.
Uyet Inc. is a Shibuya-based company led by representative director Daiki Kajita, describing itself as an IP content trading company. Its three most recent stories show work in three separate directions: research into streamer health, skill training for streamers, and offline fan events tied to regional content.
The newest is a survey published on September 28 on VTuber activities, lifestyle, and health. The online clinic service haico Online Clinic ran the study, which covered 311 VTubers and V-livers across 26 questions on daily rhythm, sleep, diet, exercise, physical symptoms, mental health, medical consultations, and willingness to keep streaming. About 67 percent of respondents reported mental health issues tied to streaming activity, and many said they keep working while in poor physical condition. The results point to a gap between the number of streamers reporting distress and the number who stop to rest.
Training runs on a separate track. Uyet held a free VTuber-focused voice training webinar on August 28 at 7:00 PM, the second installment of the series after a July edition that drew many applications and a positive response. Instructor Kakuyo Hatena, a former corporate VTuber with over 1 million subscribers, covered voice types and exercises for home practice.
The Machi Supacha Project with Niimi City, meanwhile, moves online fandom into local activity. On October 23, 2026, uyet will host a volunteer cleanup at Yumesuki Park in Niimi City, Okayama Prefecture, a location visited by VTuber Shigure Mito and featured in a vlog from the project. The 90-minute session from 14:00 to 15:30 includes cleaning the park, painting, and trash collection, free to join with a capacity of 10 people and a lottery if applications exceed it. The project has run in eight municipalities so far, including Niimi City.
